Citrine sphere with rainbows

This natural citrine quartz sphere is a beautifully luminous piece, alive with soft golden tones and vibrant internal rainbow refractions. Its warm glow and shifting flashes of colour create an elegant yet captivating display, making it a standout addition to any collection.

Expertly polished into a smooth sphere, this piece allows light to travel evenly throughout the crystal, enhancing its internal features from every angle. Fine internal fractures and inclusions interact with light to produce vivid rainbow flashes that appear and disappear as the sphere is moved, giving it a dynamic and ever-changing quality.

The colour ranges from pale lemon to warm golden hues, with natural tonal variation that adds depth and character. The combination of clarity and internal features creates a beautiful balance between transparency and light play, resulting in a softly radiant and visually engaging piece.

Geological & Scientific Notes
Citrine is a variety of quartz coloured by trace amounts of iron within its structure. Its warm yellow tones develop naturally through geological heating processes over long periods.

The vibrant rainbow refractions seen within this piece are created when light passes through internal fractures and microscopic inclusions. These natural features disperse light into spectral colours, producing shifting flashes that change depending on viewing angle and lighting conditions.

Clarity varies throughout the sphere, with internal inclusions playing an important role in generating the strong rainbow effect. These features are entirely natural and contribute to the individuality and visual appeal of the crystal.

The spherical shape enhances the distribution of light, allowing the rainbows and internal structures to be visible from all angles, giving the piece a balanced and radiant presence.
